Focal facial dermal dysplasia type III (FFDD3) is a rare focal facial facial dysplasia (FFDD; see this term), characterized primarily by congenital bitemporal scar-like depressions and a typical, but variable facial dysmorphism, which may include distichiasis (upper lids) or lacking eyelashes, slanted eyebrows and a flattened and/or bulbous nasal tip and other features such as a low frontal hairline, sparse hair, redundant skin, epicanthal folds, low-set dysplastic ears, blepharitis and conjunctivitis.

Shashi-Pena syndrome is a neurodevelopmental syndrome characterized by delayed psychomotor development, variable intellectual disability, hypotonia, facial dysmorphism, and some unusual features, including enlarged head circumference, glabellar nevus flammeus, and deep palmar creases. Some patients may also have atrial septal defect, episodic hypoglycemia, changes in bone mineral density, and/or seizures (summary by Shashi et al., 2016).

MRD57 is an autosomal dominant neurodevelopmental disorder with a highly variable phenotype. Most affected individuals have delayed psychomotor development apparent in infancy or early childhood, language delay, and behavioral abnormalities. Additional features may include hypotonia, feeding problems, gastrointestinal issues, and dysmorphic facial features (summary by Reijnders et al., 2018).

Mental retardation and microcephaly with pontine and cerebellar hypoplasia (MICPCH) is an X-linked disorder affecting females and characterized by severe intellectual disability, microcephaly, and variable degrees of pontocerebellar hypoplasia. Affected individuals have very poor psychomotor development, often without independent ambulation or speech, and axial hypotonia with or without hypertonia. Some may have sensorineural hearing loss or eye anomalies. Dysmorphic features include overall poor growth, severe microcephaly (-3.5 to -10 SD), broad nasal bridge and tip, large ears, long philtrum, micrognathia, and hypertelorism (summary by Moog et al., 2011).

Hypotonia, ataxia, and delayed development syndrome (HADDS) is a neurodevelopmental syndrome characterized by congenital hypotonia, delayed psychomotor development, variable intellectual disability with speech delay, variable dysmorphic facial features, and ataxia, often associated with cerebellar hypoplasia. Some patients may have urogenital abnormalities (summary by Sleven et al., 2017).
